Julu 橘錄, also called Yongjia julu 永嘉桔錄 "Tangerines of Yongjia", is a book on citriculture written during the Southern Song period 南宋 (1127-1279) by Han Yanzhi 韓彥直 (jinshi degree 1148). Han Yanzhi climbed up the ladder of official career up to the post of Minister of Works (gongbu shangshu 工部尚書) and Grand Master of Splendid Happiness (guanglu dafu 光祿大夫). He died in high honours as Commandery Duke of Qichun 蘄春郡公. Han Yanzhi also wrote the book Xinshuijing 水心鏡.
The 3-juan-long Julu was written when Han was prefect of Wenzhou 溫州, Zhejiang. Yongjia, as it appears in title, is another name for the city of Wenzhou. In his preface, dated 1178, Han explained the reason why he wrote a book on tangerines.
The first chapter includes a detailed description of appearance, colours and taste of eight kinds of mandarin oranges (gan 柑) and one kind of orange (cheng 橙), of which the nishanru 泥山乳 is rated the best. The middle fascicle describes 18 kinds of yellow tangerines (huangju 黃橘), while the last chapter is dedicated to the cultivation and use of these kinds of citrus fruits, like hybridization, planting, raising, protecting from diseases, watering, plucking, storing and treatment of the fruits, and how to use them as food or medicine.
The Julu is included in the series Baichuan xuehai 百川學海, Shuofu 說郛, Han-Wei congshu 漢魏叢書 and Siku quanshu 四庫全書.
